You cannot rationally believe in an infinitely loving God unless you accept Jesus as proof.

You can believe in God without believing in Jesus. You can even believe that God is kindly, caring, and compassionate without believing in Jesus – we experience beauty, after all, and times of joy and wonder.

But you cannot rationally believe God is all-loving without believing in Jesus, because the weight of the evidence is otherwise: war, cruelty, injustice, and the final, impeccable witness, death.
